Herpyllus ecclesiasticus, commonly called the eastern parson spider, is a species of spider named after the abdominal markings resembling an old-style cravat worn by clergy in the 18th century.[1] It is mainly found in North America east of the Rocky Mountains, from Alberta, Canada, east to Nova Scotia, and south to Tamaulipas, Mexico, and Florida, US.[2] [3] Individuals can be found throughout the year, both in homes and under rocks or logs in deciduous forests.[3]
Individuals are covered with black hairs on the cephalothorax and gray hairs on the abdomen. On the back is the distinctive white mark that gives the species its common name; there is a small white spot above the spinnerets.[1]
During the day, individuals reside in silken retreats. They emerge to hunt at night.[1]
Bites are painful, and some individuals may experience an allergic reaction.[1]
